Cornerstone Building Brands announced that Mastic®️ by Ply Gem®️ Structure®️ Home Insulation System™ Siding was named a winner in the Exterior Renovation category of Good Housekeeping’s 2026 Home Reno Awards. The full list of awards can be found at goodhousekeeping.com/home-renovation-awards-2026.
Mastic®️ by Ply Gem®️ Structure®️ Home Insulation System™ Siding features an exclusive combination of vinyl siding technologies and high-performance breathable foam that limits temperature transfer – keeping homes warmer in the winter and cooler in the summer. The system wraps the home in a continuous blanket of insulation up to 1 ¼” thick with an R-value of up to 3.0 — slowing the release of cool or warm air from the home during power outages. Additionally, the EPS insulation is 300 percent more impact-resistant than standard vinyl siding, offering extreme protection from hail and ice storms.

“We are honored to receive this recognition from Good Housekeeping,” said Jeremy Harris, general manager – vinyl for the Siding and Accessories business unit of Cornerstone Building Brands. “The Mastic® by Ply Gem® Structure® Home Insulation System™ Siding was designed with durability in mind — helping homeowners increase energy efficiency, protect their homes from extreme weather and reduce long-term maintenance. This award validates Cornerstone Building Brands’ commitment to sustainability, innovation and delivering home exterior solutions that maximize performance and underscores Mastic’s position as the leading brand in the vinyl siding category.”
Minimizing heat or cooling loss through the building envelope is crucial for both home comfort and financial savings. Proper weatherization is essential for homeowners to ensure their properties can endure below-freezing temperatures in the winter and heat waves in the summer. Mastic®️ by Ply Gem®️ Structure®️ Home Insulation System™ not only covers exterior walls with a layer of continuous insulation; it also covers problem areas around windows, doors and corners with a range of insulated accessories. EPS foam is a breathable material that allows water vapor to escape, preventing moisture buildup and helping to inhibit mold and mildew growth.
Unlike wood, stucco or fiber cement, Mastic®️ by Ply Gem®️ Structure®️ Home Insulation System™ never needs painting or staining, which saves time and money year after year. Additionally, the vinyl in the panels is derived from two natural resources: salt (57 percent) and natural gas (43 percent) and is also made with recycled materials to conserve resources.
